Preparation of highly efficient antibacterial non-woven by facile plasma-induced graft polymerizing of DADMAC

The development of surface modification technology for temperature sensitive fibers has been a huge challenge. In this work, a novel technique based on cold plasma treatment was developed for the preparation of anti-bacterial polypropylene(PP) fibers. The results showed that plasma treatment introduced a rough surface and polar groups, which acted as the anchor point and initiators for diallyldimethyl ammonium chloride(DADMAC) graft-polymerization. The fabricated PP membranes presented a high ba...
